Insights

A recent outbreak of glanders, a contagious equine disease with zoonotic potential, occurred in India. Control measures were successful in Maharashtra, but the infection

Area of Science:

  • Veterinary Microbiology
  • Zoonotic Diseases
  • Epidemiology

Background:

  • Glanders is a highly contagious, notifiable disease affecting equids, caused by Burkholderia mallei.
  • It poses significant zoonotic risks and was previously confined to specific regions in India.
  • A notable outbreak recently emerged in Maharashtra, India.

Purpose of the Study:

  • To report and analyze a major outbreak of glanders in equids in Maharashtra, India.
  • To detail the diagnostic methods and control strategies employed.
  • To assess the effectiveness of control measures and identify potential sources of infection.

Main Methods:

  • Clinical examination of affected equids.
  • Laboratory analysis of serum, nasal swabs, and pus samples.
  • Isolation of Burkholderia mallei.
  • Complement Fixation Test (CFT) for serological diagnosis.
  • Implementation of control strategies as per the Glanders and Farcy Act, 1899.

Main Results:

  • Glanders was confirmed in equines in Pune and Panchgani areas of Maharashtra.
  • Burkholderia mallei isolates were obtained from pus and nasal swabs.
  • 23 serum samples tested positive for glanders via CFT.
  • The outbreak was successfully controlled in Maharashtra.
  • Subsequent surveillance of over 3,500 equines showed negative results.

Conclusions:

  • The outbreak in Maharashtra was effectively managed using established control protocols.
  • Despite successful containment, the possibility of the infection's origin in North India warrants further investigation.
  • Continued vigilance and surveillance are crucial for preventing future outbreaks of this zoonotic disease.

Infectious Diseases and Their Occurrence

Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable temporal or...

Investigation of Disease Outbreaks

Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...
Clinical Significance of Antibiotic Resistance01:25

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...
Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

Bacterial Gastroenteritis

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
